What is it?
When the Audi A7 was introduced in 2010 its fastback coupé styling and five-door package proved to be a compelling combination.
The standard 268bhp 3.0-litre TDI engine has been substantially upgraded to improve efficiency and reduce fuel consumption, and is being introduced to the A7 range for the first time.
Audi's Ultra version is calibrated to further optimise fuel consumption and CO2. There’s less power at 215bhp but torque is still a plentiful 295lb ft.
The trade-off is worth it in terms of economy though, with the Ultra returning 60.1mpg compared to 54.3mpg for the more powerful engine.
CO2 emissions are correspondingly lower too, at 122g/km rather than 136g/km. SCR (selective catalyst reduction) means the Ultra meets Euro 6 emissions standards and earns ‘clean diesel’ status too.
